Today we are going to talk briefly about virtualization. This is the concept of allowing one physical computer to act as many virtual computers. We will explain what that means in more detail and also uncover the role of hypervisors in this process. We will then uncover the two kinds of hypervisors before explaining why people use virtualization technology: for security, money savings, and its flexibility and potential in disaster recovery of data. Read on to learn more about these six key facts related to virtualization.
1. Virtualization Allows One Computer to Act as Many
Virtualization is a technology that lets one physical computer act like many virtual ones. This technology helps to use a computer’s power efficiently by creating isolated virtual machines (VMs). These VMs, or virtual servers, run separately with their own software, just like real computers do. This saves money and increases flexibility, as you can run different systems and apps independently on one machine.
2. Hypervisors Create and Run VMs
A hypervisor, or a virtual machine manager, is a key part of virtualization. But if you are wondering “What is a Hypervisor?”, you’re not alone. Let’s break this down clear and simple. The hypervisor creates and runs the VMs. It manages how these virtual machines use a computer’s resources, like the central processing unit (CPU) and memory.
3. There Are Bare Metal and Hosted Hypervisors
There are two types of hypervisors: bare metal hypervisors work directly on the computer’s hardware and are faster and more efficient, while hosted hypervisors run on top of an existing operating system. The hypervisor ensures everything runs smoothly and securely.
4. People Use Virtualization Technology for Security
People use virtualization tech for the sake of isolation and security of their important data and information. They use this tech to create separate and disconnected virtual environments as this enhances digital security. Keeping applications and data separate reduces the risks of security breaches and lost or stolen data.
5. Virtualization is Cost-Effective for Businesses
By combining several servers into VMs on a single physical server, businesses can reduce expenditures on hardware, electricity, floor space, and tech maintenance management. This means businesses can run with fewer physical machines, a modern solution that offers significant cost savings.
6. VMs Are Flexible and Backed Up
Finally, VMs carry important and private data. They must be kept safe and backed up at all times. They are software files that can be backed up, duplicated, and uploaded to other physical machines. This means if you have an issue with one physical machine, your VMs are still safe on another, ready for use. This makes VMs accessible, scaleable, moveable, and efficient in terms of disaster recovery.
We have explained that virtualization and hypervisors let one computer do the work of many, making computing more efficient, secure, and cost-effective. Hypervisors create and run virtual machines and there are two kinds of hypervisors: bare metal and hosted. People use this clever tech for security purposes, as VMs do not share data. Moreover, virtualization is a cost-effective way to reduce spending on running physical computers and their maintenance. Last but not least, VMs are flexible and transferable.
They can be duplicated, imported to other computers, and accessed even when a physical computer is down. They are handy for disaster recovery and overall make business processes more efficient.
